DETAILED DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS
The following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
In order to make the advantages of the technical solutions of the present invention more clearly, the following describes in detail the present invention with reference to the accompanying drawings and the embodiments.
An embodiment of the present invention provides an application distribution method, and as shown in FIG. 1, the method includes the following steps.
101. A first terminal sends a distribution request to an application distribution server.
The distribution request at least carries a user identifier, a requested service category, and a hardware feature and/or a software feature of a terminal device, where the user identifier includes: a user telephone number and/or ID information, the hardware feature of the terminal device includes: a manufacturer serial number, and the software feature of the terminal device includes: an operating system version number.
102. When the distribution request satisfies a preset criterion of the application distribution server, the first terminal receives at least one propagation code sent by the application distribution server.
Optionally, the distribution request satisfying the preset criterion of the application distribution server includes that: if the requested service category belongs to a service category included in the application distribution server, and the manufacturer serial number of the terminal device and/or the operating system version number of the terminal device is the same as a set manufacturer serial number and/or operating system version number of the application distribution server, the distribution request satisfies the preset criterion of the application distribution server.
Optionally, when the distribution request does not satisfy the preset criterion of the application distribution server, a failure message sent by the application distribution server is received, and the distribution applying process is stopped.
Optionally, one or more propagation codes may be sent to the first terminal.
103. The first terminal sends the propagation code to a second terminal, so that the second terminal applies, according to the propagation code, to the application distribution server for installation and registration of an application and running and tracking of the application.
Optionally, the sending the propagation code to a second terminal includes sending the propagation code to the second terminal through short-distance communication. Alternatively, the propagation code is sent to the Internet, so that the second terminal acquires the propagation code.
The propagation code is used for identifying a category of an application, describing a feature of the application, and identifying the first user identifier and a propagation sequence number. The first user identifier is used for indicating from which terminal the propagation code is propagated, that is, indicating which propagation channel of the propagation code is used. The propagation sequence number is identifier information generated by the application distribution server when the application distribution server sends the propagation code. Whenever delivering a propagation code, the application distribution server adds the propagation sequence number by 1. For example, if the propagation sequence number of the first propagation code delivered by the application distribution server after initialization is 0, the propagation sequence number of the second delivered propagation code is 1, and the rest can be deduced by analog. Meanwhile, the application distribution server records the propagation sequence number in the propagation code and on the server side, so that when the second terminal uses the propagation code to apply for registration, the application distribution server can rapidly find corresponding application content. The application may be a soft SIM card.
Compared with the prior art, in this embodiment of the present invention, a terminal sends a distribution request to an application distribution server, receives, when the request satisfies a preset criterion of the application distribution server, a propagation code sent by the application distribution server, and propagates the propagation code through short-distance communication or the Internet to a second terminal for use, so that the second terminal applies, according to the propagation code, to the application distribution server for installation and registration of an application and running and tracking of the application. This solves the problem that the terminal can only act as a subscriber of an application, and the terminal changes from a subscriber to a propagator, which expands a propagation channel of the application.
Still another embodiment of the present invention provides an application distribution method, and as shown in FIG. 2, the method includes the following steps.
201. An application distribution server receives a distribution request sent by a first terminal.
The distribution request at least carries a user identifier, a requested service category, and a hardware feature and/or a software feature of a terminal device, where the user identifier includes: a user telephone number and/or ID information, the hardware feature of the terminal device includes: a manufacturer serial number, and the software feature of the terminal device includes: an operating system version number.
202. When the distribution request satisfies a preset criterion, the application distribution server sends at least one propagation code to the first terminal.
Optionally, the distribution request satisfying the preset criterion includes that:
if the requested service category belongs to a service category included in the server, and the manufacturer serial number of the terminal device and/or the operating system version number of the terminal device is the same as a set manufacturer serial number and/or operating system version number of the server, the distribution request satisfies the preset criterion.
Optionally, when the distribution request does not satisfy the preset criterion, a failure message is sent to the first terminal.
Optionally, one or more propagation codes may be sent to the first terminal.
Further, after a second terminal acquires the propagation code, the method further includes receiving, by the application distribution server, a registration request sent by the second terminal. The registration request at least carries the propagation code and a second user identifier.
Further, the method further includes: receiving, by the application distribution server, a running and tracking request sent by the second terminal, where the running and tracking request at least carries the propagation code and the second user identifier.
The propagation code is used for identifying a category of an application, describing a feature of the application, and identifying the first user identifier and a propagation sequence number. The first user identifier is used for indicating from which terminal the propagation code is propagated, that is, indicating a specific propagation channel of the propagation code. The propagation sequence number is identifier information generated by the application distribution server when the application distribution server sends the propagation code. Whenever delivering a propagation code, the application distribution server adds the propagation sequence number by 1. For example, if the propagation sequence number of the first propagation code delivered by the application distribution server after initialization is 0, the propagation sequence number of the second delivered propagation code is 1, and the rest can be deduced by analog. Meanwhile, the application distribution server records the propagation sequence number in the propagation code and on the server side, so that when the second terminal uses the propagation code to apply for registration, the application distribution server can rapidly find corresponding application content. The application may be a soft SIM card.
Further, after the receiving a registration request sent by the second terminal, the method further includes: sending soft SIM card data to the second terminal.
Compared with the prior art, in this embodiment of the present invention, an application distribution server determines a distribution request of a first terminal and sends a propagation code to the first terminal when the distribution request satisfies a preset criterion, so that the first terminal sends the propagation code to a second terminal for use. This increases a propagation channel of an application and solves the problem that the application distribution server can only provide an application download service for a terminal instead of providing an application distribution service, and more application propagation channels are provided for the terminal.
Still another embodiment of the present invention provides an application distribution method, and as shown in FIG. 3, the method includes the following steps.
301. A second terminal acquires a propagation code released by a first terminal.
Optionally, the acquiring a propagation code released by a first terminal includes receiving the propagation code from the first terminal through short-distance communication; or acquiring, through the Internet, the propagation code released by the first terminal.
302. The second terminal sends a registration request to an application distribution server to apply for installation and registration of an application, where the registration request at least carries the propagation code and a second user identifier.
303. After the registration is successful and whenever the application runs, the second terminal sends a running and tracking request to the application distribution server, where the running and tracking request at least carries the propagation code and the second user identifier.
The application may be a soft SIM card.
Further, after the sending a registration request to an application distribution server, the method further includes receiving soft SIM card data sent by the application distribution server, and importing the soft SIM card data into a soft SIM card application.
Compared with the prior art, in this embodiment of the present invention, a second terminal acquires a propagation code released by a first terminal, then applies, according to the propagation code, to an application distribution server for registration of a particular application, receives and saves related data after obtaining permission of the application distribution server, imports the propagation code into the application when a user needs to use the application, and sends a running and tracking request to the application distribution server whenever the application runs, so that the application distribution server maintains a use condition of the application. This solves the problem that an application acquiring channel of a terminal is limited, and the terminal can conveniently and rapidly acquire a desired application through another terminal, which avoids a waste of time in searching among multiple applications in an application store and improves user experience.
Still another embodiment of the present invention provides an application distribution method, in which a soft SIM (Subscriber Identity Module, subscriber identity module) card application is used as an example. A terminal installs a soft SIM card, applies to an application distribution server for a propagation code, and propagates the propagation code to another terminal, so that the another terminal downloads the soft SIM card from the application distribution server and registers the soft SIM card to the application distribution server. As shown in FIG. 4, the method includes the following steps.
401. A terminal downloads and installs a soft SIM card.
For example, a soft SIM card may be purchased and downloaded from a frequently visited on-line application store and installed, or purchased, downloaded, and installed through software such as a phone assistant. A server of the on-line store or the phone assistant may be regarded as a specific form of an application distribution server. Before providing download for a terminal, the application distribution server needs to send a soft SIM card application acquiring request to an operator and applies for a soft SIM program.
For example, the application acquiring request at least carries: a content type, a content identifier, and the quantity of an applied application. The content type includes: an executable code and soft SIM card data; when the executable code of the application already exists in the server, the content type can only include the soft SIM card data. The content identifier is used for indicating a specific category of the applied application, for example, soft SIM card application, map, book, or game. The quantity refers to the quantity of executable codes and soft SIM card data that are returned by the operator. As for the application distribution server side, the quantity of the executable codes is generally 1 because an executable code is the main part of an application, the main part of the application downloaded from the application distribution server by different terminal users that download the same application is the same, and only the soft SIM card data differs according to different requirements of the users on a program function.
It should be noted that different from a physical SIM card currently used by a user, a soft SIM card is a virtual SIM card program, and a user can use the soft SIM card to implement a communication service after simple authorization and installation just like using the physical SIM card. For a user who intends to change a card, for example, to switch between SIM cards of different operators in a country, or to use a local SIM card when going abroad so as to avoid expensive roaming fees, it is inconvenient to buy a replaceable SIM card instantly. Especially in a foreign country, the purchase of a SIM card may be rather troublesome due to unfamiliarity of a local language and a purchase process. The use of a soft SIM card is relatively much easier. The user can purchase soft SIM card programs of different operators in advance, and download the programs to the terminal. When a communication service of a certain operator is required, the user only needs to run a corresponding application or switch corresponding soft SIM card data.
Optionally, content of a soft SIM card application is shown in Table 1:









TABLE 1

The executable code is an application downloaded to a terminal. The propagation code is acquired from another terminal or the Internet, which identifies a way of acquiring the executable code or acquiring the executable code and the soft SIM card data. The soft SIM card data is data organized according to a related international standard and is similar to data in a hard SIM card.
It should be noted that before the application distribution server acquires an application from an operator, the application distribution server needs to establish secure communication connection with a device of the operator, for example, the application distribution server and the device of the operator may be connected by using a P1 interface and through the public Internet or a VPN (Virtual Private Network, virtual private network), interaction between the two follows transmission protocols such as the TCP (Transmission Control Protocol, Transmission Control Protocol)\HTTP (Hyper Text Transport Protocol, Hypertext Transport Protocol)\HTTPS (Hyper Text Transfer Protocol Secure, Hyper Text Transfer Protocol Secure), and transmitted content is a formatted message. Then, the application distribution server needs to register to and log in to the device of the operator to obtain authentication of the device of the operator.
Optionally, if an application corresponding to a category or content of the application requested by the application distribution server side does not exist in a system warehouse of the operator, the operator may return a failure message to the application distribution server, and the application distribution server ends the application acquiring request process according to the failure message.
Optionally, the application distribution server may acquire applications from multiple operators, and to better manage the acquired applications by category, an application warehouse that is used specially for saving application data needs to be established on the application distribution server side.
402. After running the soft SIM card application, the terminal sends a distribution request to the application distribution server.
For example, the distribution request at least carries: a user identifier, a requested service category, and a hardware feature and/or a software feature of a terminal device. The user identifier may be a mobile phone number used by a user or a user name of the soft SIM card registered by the user and is used for indicating identity information of the user; the requested service category is corresponding to the service category of the soft SIM card; and the hardware feature and/or software feature of the terminal device is used for indicating whether the terminal is qualified for applying for distribution, for example, the hardware feature may be a manufacturer serial number of the terminal, and the software feature may be the version number of an operating system used by the terminal.
It should be noted that before the terminal sends the distribution request to the application distribution server, the terminal needs to establish secure communication connection with the application distribution server, for example, the terminal and the application distribution server may be connected by using a P2 interface and through the public Internet, interaction between the two follows transmission protocols such as the TCP (Transmission Control Protocol, Transmission Control Protocol)\HTTP (Hyper Text Transport Protocol, Hypertext Transport Protocol)\HTTPS (Hyper Text Transfer Protocol Secure, Hyper Text Transfer Protocol Secure), and transmitted content is a formatted message. Then, the terminal needs to register to and log in to the application distribution server by using the application.
403. The application distribution server determines whether the distribution request satisfies a preset criterion.
Optionally, if the requested service category of the terminal belongs to a service category included in the application distribution server, and the manufacturer serial number of the terminal device and/or the operating system version number of the terminal device is the same as a set manufacturer serial number and/or operating system version number of the application distribution server, the distribution request satisfies the preset criterion of the application distribution server. If the requested service category of the terminal does not belong to a service category included in the application distribution server, or the manufacturer serial number of the terminal device and/or the operating system version number of the terminal device is different from a set manufacturer serial number and/or operating system version number of the application distribution server, the distribution request does not satisfy the preset criterion of the application distribution server.
404. When the distribution request satisfies the preset criterion, the application distribution server sends a propagation code to the terminal.
Optionally, when the distribution request does not satisfy the preset criterion, send a failure message to the terminal, so that the terminal ends the distribution applying process.
The propagation code is used for identifying a category of an application, describing a feature of the application, and identifying the first user identifier and a propagation sequence number. For example, the propagation code identifies a category of a soft SIM card and is attached with a text description used to describe a function and a feature of the soft SIM card, so that the user that does not install the soft SIM card can have a general understanding of the soft SIM card application after obtaining the propagation code. The first user identifier is used for indicating from which terminal the propagation code is propagated, that is, indicating a specific propagation channel of the propagation code. For example, the first user identifier may be an identifier of a terminal user that distributes the propagation code, and may be a download network address of the soft SIM card, for example, a network address of a forum, a network address of an application store, or a download address of the soft SIM card in the application distribution server. The propagation sequence number is identifier information generated by the application distribution server when the application distribution server sends the propagation code. Whenever delivering a propagation code, the application distribution server adds the propagation sequence number by 1. For example, if the propagation sequence number of the first propagation code delivered by the application distribution server after initialization is 0, the propagation sequence number of the second delivered propagation code is 1, and the rest can be deduced by analog. Meanwhile, the application distribution server records the propagation sequence number in the propagation code and on the server side, so that when a second terminal uses the propagation code to apply for registration, the application distribution server can rapidly find corresponding application content.
Optionally, the application distribution server may send one or more propagation codes to the terminal, and a specific quantity of the propagation codes is decided by the distribution request of the terminal.
405. After receiving the propagation code, the terminal propagates the propagation code to the second terminal.
Optionally, when the terminal is close to the second terminal, the terminal and the second terminal may be associated through short-distance communication, for example, through WiFi (Wireless Fidelity, wireless fidelity), Bluetooth, NFC (Near Field Communication, near field communication), or the like; and after the association, the terminal directly sends the propagation code and a soft SIM card application corresponding to the propagation code to the second terminal; or, the terminal sends, through the Internet, the propagation code and a soft SIM card application corresponding to the propagation code to various network forums or social networks for download by the second terminal in need.
Optionally, the second terminal may only acquire one propagation code among the propagation codes obtained by the terminal in step 404, and may also acquire multiple propagation codes among the propagation codes obtained by the terminal in step 404. Each propagation code may be used to generate one or more telephone numbers.
It should be noted that communication connection between the terminal and the second terminal may be established by using a P3 interface, interaction between the second terminal and the terminal follows transmission protocols such as the TCP (Transmission Control Protocol, Transmission Control Protocol)\HTTP (Hyper Text Transport Protocol, Hypertext Transport Protocol)\HTTPS (Hyper Text Transfer Protocol Secure, Hyper Text Transfer Protocol Secure), and transmitted content is a formatted message.
406. The second terminal acquires the propagation code and the soft SIM card application, starts to install the application, and sends a registration request to the application distribution server according to the propagation code in the installation process, so as to apply for installation and registration of the application.
The registration request at least carries the propagation code and a second user identifier. The propagation code is used for indicating, to the application distribution server, that the second terminal intends to purchase a soft SIM card service and a function of the soft SIM card service to be purchased, where the soft SIM card service may be corresponding to multiple propagation codes. The propagation code is used for identifying a category of an application and describing a feature of the application, and function rights of soft SIM cards downloaded and registered by the terminal according to different propagation codes are different. The second user identifier is used for indicating the identity of the second terminal, so that the application distribution server sends the soft SIM card data to the second terminal.
407. The application distribution server prepares, for the second terminal, soft SIM card data corresponding to the propagation code.
408. The application distribution server sends a report message to the operator. This step is optional.
The report message is used for notifying the operator that a new user subscribes to a service, so that the operator makes service preparation for providing a corresponding data service for the user of the second terminal.
409. The operator returns a preparation complete message to the application distribution server. This step is optional.
410. The application distribution server sends the prepared soft SIM card data to the second terminal.
411. The second terminal imports the soft SIM card data into the soft SIM card application.
Optionally, whenever the soft SIM card program runs, the second terminal needs to send a running and tracking request to the application distribution server, so that the application distribution server tracks a use condition of the soft SIM card used by the second terminal.
Optionally, the application distribution server may also obtain the running and tracking information from the operator and does not require the second terminal to report the running and tracking information.
It should be noted that the propagation code identifies a propagation channel, that is, from where the propagation code is propagated. In this embodiment, when the second terminal uses the propagation code for registration, the operator can learn that the propagation code used by the second terminal is propagated by the terminal, and when the second terminal pays for using the soft SIM card, the operator can provide proper profit sharing for the terminal, so as to encourage the terminal to propagate the soft SIM card. In this way, a new service can be rapidly promoted for the operator.
Compared with the prior art, in this embodiment of the present invention, a terminal first installs a soft SIM card application and applies to an application distribution server for a propagation code, receives, after a criterion of the application distribution server is satisfied, the propagation code sent by the application distribution server, and then propagates the propagation code to a second terminal through short-distance communication or the Internet, so that the second terminal acquires the propagation code; finally, the second terminal acquires the propagation code, sends a registration request to the application distribution server according to the propagation code to apply for installation and registration of an application, and completes the application distribution process. The second terminal can also initiate a distribution request to the application distribution server, and if the distribution request satisfies the preset criterion of the application distribution server, the second terminal can also acquire the propagation code and propagate the propagation code to another terminal. The application distribution method provided in the present invention solves the problem that it is difficult for a user to acquire an application due to a limited acquiring channel. The user changes from a subscriber of an application to a propagator of the application, which significantly increases a propagation channel of the application, develops potential clients, and improves user experience and propagation efficiency of the application.
